Chemistry Solutions and Concentrations

These flashcards provide definitions and explanations of key terms related to solutions and their concentrations in chemistry.

Solution

A homogeneous mixture of two or more substances where one substance, the solvent, dissolves another substance, the solute.

Solvent

The dissolving medium in a solution.

Solutes

Substances that are dissolved in a solvent to form a solution.

Aqueous solutions

Solutions in which water is the dissolving medium or solvent.

Saturated

A solution that contains as much solute as can be dissolved in that solution.

Unsaturated

A solution in which more solute can be dissolved than is already dissolved.

Concentrated

A solution in which a relatively large amount of solute is dissolved.

Dilute

A solution where a relatively small amount of solute is dissolved.

Mass percent

A way to express the concentration of a substance in a mixture or solution, also called weight percent.

Molarity (M)

Moles of solute per volume of solution in liters.

Standard solution

A solution in which the concentration is accurately known.

Dilution

The process of adding solvent to lower the concentration of solute in a solution.

Neutralization reaction

An acid-base reaction.
